Hello,
Opened a Canon Raw CR2 file into ACR version 12.0.0.322 (came with PS 2020) and was able to make normal adjustment in all of the panels. However, when I went into HSL panel to make some adjustments nothing would happen when I would move a slider in any of the panels Hue, Saturation, Luminance. I notice when moving a slider (either panel) I would see the yellow triangle exclamation point warning symbol appearing in the photo icon on the left panel of ACR. Continued to try moving all sliders in the HSL, but nothing changed and kept getting the yellow triangle warning in the photo icon. I'm using an iMac 27 inch with Mojave 10.14.6. I have 32 GB Ram, 1TB hard drive with 495 GB free. My color card is NViDIA GeForce GTX 660M, 512MB Ram.
Any Help solving this issue will be greatly appreciated.
Dennis
